Tom Tromey 3f77c7691f PR python/13598 - add before_prompt event
This adds an event that is emitted just before GDB presents a prompt
to the user.  This provides Python code a way to react to whatever
changes might have been made by the previous command.  For example, in
my GUI I use this to track changes to the selected frame and reflect
them in the UI.

Built and regtested on x86-64 Fedora 23.

Luis Machado 5cf30ebf64 Improve load command's help text
This fairly obvious patch adds usage text to the load command's help text.

Originally it did not have usage and mentioned things like FILE and OFFSET
without explaining how those should be passed in the command.

Martin Galvan 18da0c51da PR gdb/21122: Fix documentation mistakes for breakpoint commands
Currently, the breakpoint documentation refers to some commands taking breakpoint
"ranges" as arguments. We discussed this with Pedro and concluded that it would
be more accurate to speak in terms of breakpoint "lists", whose elements can optionally
be ranges. I also fixed a couple of minor mistakes in the docs.

gdb/ChangeLog:

	* breakpoint.c (_initialize_breakpoint): Update the help description
	of the 'commands' command to indicate that it takes a list argument.

gdb/doc/ChangeLog:

	* gdb.texinfo (Breakpoints): Reword documentation to speak in terms of
	space-separated breakpoint lists.  Also add a missing @table command
	and @cindex for breakpoint lists.

Luis Machado 78cbbba8e0 Add command to erase all flash memory regions
Changes in v4:

- Replaced phex call with hex_string.

Changes in v3:

- Addressed comments by Pedro.
- Output of memory region size now in hex format.
- Misc formatting fixups.
- Addressed Simon's comments on formatting.
- Adjusted command text in the manual entry.
- Fixed up ChangeLog.
- Renamed flash_erase_all_command to flash_erase_command.

Changes in v2:

- Added NEWS entry.
- Fixed long lines.
- Address printing with paddress.

Years ago we contributed flash programming patches upstream.  The following
patch is a leftover one that complements that functionality by adding a new
command to erase all reported flash memory blocks.

The command is most useful when we're dealing with flash-enabled targets
(mostly bare-metal) and we need to reset the board for some reason.

The wiping out of flash memory regions should help the target come up with a
known clean state from which the user can load a new image and resume
debugging. It is convenient enough to do this from the debugger, and there is
also an MI command to expose this functionality to the IDE's.

This has been tested for the n64 and o32 ABIs.  Signal frame unwinders for
both ABIs are provided.  FreeBSD/mips requires custom linkmap offsets since
it contains an additional l_off member in 'struct link_map' that other

Pedro Alves df3ee9ca89 Support an "unlimited" number of user-defined arguments
New in v2:

  - A few adjustments / simplifications were possible now that we
    require C++11:

    . Use std::unique_ptr to make the user_args_stack std::vector own
      its elements:

       static std::vector<std::unique_ptr<user_args>> user_args_stack;

    . use vector::emplace_back to construct elements directly in the
      corresponding vectors.

    . use std::to_string instead of adding a gdb::to_string
      replacement.

  - Now includes a test.

Docs/NEWS are unchanged from v1 and have already been approved.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I recently wrote a user-defined command that could benefit from
supporting an unlimited number of arguments:

 http://palves.net/list-active-signal-handlers-with-gdb/

E.g., 'info signal-dispositions 1 2 3 4 5 6 7 8 9 10 11'

However, we currently only support up to 10 arguments passed to
user-defined commands ($arg0..$arg9).

I can't find a good reason for that, other than "old code with hard
coded limits".  This patch removes that limit and modernizes the code
along the way:

  - Makes the user_args struct a real C++ class that uses std::vector
    for storage.

  - Removes the "next" pointer from within user_args and uses a
    std::vector to maintain a stack instead.

  - Adds a new RAII-based scoped_user_args_level class to help
    push/pop user args in the stack instead of using a cleanup.

Pedro Alves 01770bbde9 Fix PR 20559 - "eval" command and $arg0...$arg9/$argc substitution
It'd be handy to be able to iterate over command arguments in
user-defined commands, in order to support optional arguments
($arg0..$argN).

I thought I could make it work with "eval", but alas, it doesn't work
currently.  E.g., with:

 define test
   set $i = 0
   while $i < $argc
     eval "print $arg%d", $i
     set $i = $i + 1
   end
 end

we get:

 (gdb) test 1
 $1 = void
 (gdb) test 1 2 3
 $2 = void
 $3 = void
 $4 = void
 (gdb)

The problem is that "eval" doesn't do user-defined command arguments
substitution after expanding its own argument.  This patch fixes that,
which makes the example above work:

 (gdb) test 1
 $1 = 1
 (gdb) test 1 2 3
 $2 = 1
 $3 = 2
 $4 = 3
 (gdb)

New test included, similar the above, but also exercises expanding
$argc.

I think this is likely to simplify many scripts out there, so I'm
adding an example to the manual and mentioning it in NEWS as well.

Simon Marchi ad02e4fe87 Makefiles: Disable suffix rules and implicit rules
Since we don't use suffix rules nor implicit rules in gdb, we can
disable them.  The advantage is a slightly faster make [1].

Here are some numbers about the speedup.  I ran this on my trusty old
Intel Q6600, so the time numbers are probably higher than what you'd get
on any recent hardware.  I ran "make" in the gdb/ directory of an
already built repository (configured with --enable-targets=all).  I
recorded the time of execution (average of 5).  I then ran "make -d" and
recorded the number of printed lines, which gives a rough idea of the
number of operations done.

I compared the following configurations, to see the impact of both the
empty .SUFFIXES target and the empty pattern rules, as well as running
"make -r", which can be considered the "ideal" case.

 A - baseline
 B - baseline + .SUFFIXES
 C - baseline + pattern rules
 D - baseline + .SUFFIXES + pattern rules
 E - baseline + make -r

 config | time (s) | "make -d"
 -----------------------------
    A   |   5.74   |  2396643
    B   |   1.19   |   298469
    C   |   2.81   |  1266573
    D   |   1.13   |   245489
    E   |   1.01   |   163914

We can see that the empty .SUFFIXES target has a bigger impact than the
empty pattern rules, but still it doesn't hurt to disable the implicit
pattern rules as well.

There are still some mentions of implicit rules I can't get rid of in
the "make -d" output.  For example, it's trying to build .c files from
.w files:

  Looking for an implicit rule for '/home/simark/src/binutils-gdb/gdb/infrun.c'.
  Trying pattern rule with stem 'infrun'.
  Trying implicit prerequisite '/home/simark/src/binutils-gdb/gdb/infrun.w'.

and trying to build Makefile.in from a bunch of extensions:

  Looking for an implicit rule for 'Makefile.in'.
  Trying pattern rule with stem 'Makefile.in'.
  Trying implicit prerequisite 'Makefile.in.o'.
  Trying pattern rule with stem 'Makefile.in'.
  Trying implicit prerequisite 'Makefile.in.c'.
  Trying pattern rule with stem 'Makefile.in'.
  Trying implicit prerequisite 'Makefile.in.cc'.
  ... many more ...

If somebody knows how to disable them, we can do it, but at this point
the returns are minimal, so it is not that important.

I verified that both in-tree and out-of-tree builds work.

[1] Switching from explicit rules to pattern rules for files in
    subdirectories actually made it slower, so this is kind of a way to
    redeem myself.  But it the end it's faster than it was previously,
    so it was all worth it. :)

Pedro Alves 39402e6c64 gdb/doc: Remove mention of vCont's default actions
Discussion with qemu folks suggests that the vCont description could
be even simpler and clearer.  Given we now say:

 For each inferior thread, the leftmost action with a matching
 thread-id is applied.

There's really no need to even talk about "default" actions, which
raises doubts about whether "default" is special in some way (it's
not).

Specifically, what happens with multiple actions that could match a
thread, and what happens when we get a vCont action that matches a
thread that was already running.  E.g., what does:

 "vCont;s:2"
 "vCont;s:1;c"

mean for thread 2.

(Thread 2 continues stepping.)

	* gdb.texinfo (Packets): Clarify vCont packets with multiple
	actions that match a thread, and what happens when an action
	matches a thread that is already running.

Tom Tromey 9c37b5aed9 Remove Java support
This patch removes the Java support from gdb.  gcj has not seen much
development or use for years now, and was recently removed from GCC.
This patch changes gdb to follow; in the unlikely event that there are
still users using gcj, they can continue to use an older gdb to debug.
Or, they can debug in C++ mode.

Built and regtested on x86-64 Fedora 24.

Antoine Tremblay 4034d0ff52 Emit inferior, thread and frame selection events to all UIs
With this patch, when an inferior, thread or frame is explicitly
selected by the user, notifications will appear on all CLI and MI UIs.
When a GDB console is integrated in a front-end, this allows the
front-end to follow a selection made by the user ont he CLI, and it
informs the user about selection changes made behind the scenes by the
front-end.

This patch addresses PR gdb/20487.

In order to communicate frame changes to the front-end, this patch adds
a new field to the =thread-selected event for the selected frame.  The
idea is that since inferior/thread/frame can be seen as a composition,
it makes sense to send them together in the same event.  The vision
would be to eventually send the inferior information as well, if we find
that it's needed, although the "=thread-selected" event would be
ill-named for that job.

Front-ends need to handle this new field if they want to follow the
frame selection changes that originate from the console.  The format of
the frame attribute is the same as what is found in the *stopped events.

Here's a detailed example for each command and the events they generate:

thread
------

1. CLI command:

     thread 1.3

   MI event:

     =thread-selected,id="3",frame={...}

2. MI command:

     -thread-select 3

   CLI event:

     [Switching to thread 1.3 ...]

3. MI command (CLI-in-MI):

     thread 1.3

   MI event/reply:

     &"thread 1.3\n"
     ~"#0  child_sub_function () ...
     =thread-selected,id="3",frame={level="0",...}
     ^done

frame
-----

1. CLI command:

     frame 1

   MI event:

     =thread-selected,id="3",frame={level="1",...}

2. MI command:

     -stack-select-frame 1

   CLI event:

     #1  0x00000000004007f0 in child_function...

3. MI command (CLI-in-MI):

     frame 1

   MI event/reply:

     &"frame 1\n"
     ~"#1  0x00000000004007f9 in ..."
     =thread-selected,id="3",frame={level="1"...}
     ^done

inferior
--------

Inferior selection events only go from the console to MI, since there's
no way to select the inferior in pure MI.

1. CLI command:

     inferior 2

   MI event:

     =thread-selected,id="3"

Note that if the user selects an inferior that is not started or exited,
the MI doesn't receive a notification.  Since there is no threads to
select, the =thread-selected event does not apply...

2. MI command (CLI-in-MI):

     inferior 2

   MI event/reply:

     &"inferior 2\n"
     ~"[Switching to inferior 2 ...]"
     =thread-selected,id="4",frame={level="0"...}
     ^done

Internal implementation detail: this patch makes it possible to suppress
notifications caused by a CLI command, like what is done in mi-interp.c.
This means that it's now possible to use the
add_com_suppress_notification function to register a command with some
event suppressed.  It is used to implement the select-frame command in
this patch.

The function command_notifies_uscc_observer was added to extract
the rather complicated logical expression from the if statement.  It is
also now clearer what that logic does: if the command used by the user
already notifies the user_selected_context_changed observer, there is
not need to notify it again.  It therefore protects again emitting the
event twice.

No regressions, tested on ubuntu 14.04 x86 with target boards unix and
native-extended-gdbserver.

Tom Tromey 4435e1cc62 Small improvements to the remote protocol manual
I was reading the gdb RSP manual recently and I found a number of
small problems in the documentation.  This patch attempts to improve
these areas.  Specfically:

* The term "memory breakpoint" is used only in this section of the
  manual, and there inconsistently.  I found this term confusing --
  initially I thought it might be a watchpoint.  This patch changes it
  to use the term "software breakpoint", which is used in the rest of
  the manual.

* The z0 packet didn't document how "kind" was written.  And, it had a
  stray link to the architecture-specific protocol details node.  This
  patch moves this link to a better spot.

* The z1 patch didn't document that it accepts cmd_list.

* I couldn't find any text saying what response is given to a command
  like vCont in non-stop mode.  The answer is that OK is sent, and
  then a stop reply is sent as a notification.  This patch adds a note
  about this.

* The "create" stop reply did not document that the "R" argument is
  ignored.

* The "W", "X", and "w" packets did not document how the "AA" part is
  formatted.

* The %Stop notification example said "%%Stop", but I think this is
  incorrect.

2016-09-28  Tom Tromey  <tom@tromey.com>

	* gdb.texinfo (Packets) <z0>: Use "software breakpoint" rather
	than "memory breakpoint".  Further document "kind".  Move
	protocol-details link earlier.
	<z1>: Document the cmd_list argument.  Fix typo.
	<g>: Remove incorrect sentence.
	(Stop Reply Packets): Document "OK" response to requests when in
	non-stop mode.
	<swbreak>: Use "software breakpoint" rather than "memory
	breakpoint".
	<create>: Document that "R" is ignored.
	<W, X, w>: Document formatting of "AA".
	(Notification Packets): Use "%Stop", not "%%Stop".

Anton Kolesov ad0a504f7e arc: New Synopsys ARC port
ARC is a family of licensable processors developed by Synopsys.

This is an initial patch that doesn't yet support some of the features, that
are already available in Synopsys' fork of GDB, namely:

  * longjmp support
  * signal frame handling
  * prologue analysis
  * Linux targets support
  * native Linux support

ARC cores are configurable and extensible, which means from debugger
perspective that some registers and debug capabilities are optional, therefore
it is up to the GDB stub to determine exact list of register available on
target and supply it to GDB via XML target descriptions.  List of registers
that is known to GDB and is required is intentionally kept small to simplify
requirements to GDB stub and implementation of a GDB client.

This patch adds a bunch of generated files to gdb's gitignore files.
There are still a bunch of "stamp" files that are not ignored, but I

Simon Marchi 0a1ddfa6b6 Allow resetting an empty inferior-tty
This patch allows the user to set the inferior-tty to "empty", in order
to come back to the default behaviour of using the same tty as gdb is
using.

This is already supported in MI (and tested in gdb.mi/mi-basics.exp).

I added a new test, set-inferior-tty.exp, where I test only the setting
and unsetting of the parameter.  It would be nice to actually test that
the inferior output properly goes to the separate tty, but that will be
for another day.

Tom Tromey dac790e1b9 PR python/15620, PR python/18620 - breakpoint events in Python
This patch adds some breakpoint events to Python.  In particular,
there is a creation event that is emitted when a breakpoint is
created; a modification event that is emitted when a breakpoint
changes somehow; and a deletion event that is emitted when a
breakpoint is deleted.

In this patch, the event's payload is the breakpoint itself.  I
considered making a new event type to hold the breakpoint, but I
didn't see a need.  Still, I thought I would mention this as a spot
where some other choice is possible.

Tom Tromey cda75e7050 Rearrange Python breakpoint node in documentation
I noticed that the Python breakpoint documentation was ordered a bit
oddly.  It documented the constructor; then the stop method; then the
watchpoint constants (used for the constructor); then various other
methods and attributes; then the other constants used by the
constructor; and then finally some more methods and attributes.

This patch rearranges the node a little to move the constants to just
after the constructor and before the other methods and attributes.

Tom Tromey e0f3fd7c44 PR python/19293 - invalidate frame cache when unwinders change
PR python/19293 notes that when a Python unwinder is disabled, the
frame cache is not invalidated.  This means that disabling an unwinder
doesn't have any immediate effect -- but in my experience it's often
the case that I want to enable or disable an unwinder in order to see
what happens.

This patch adds a new gdb.invalidate_cached_frames function and
arranges for the relevant bits of library code to call it.  I've only
partially documented this function, considering a warning sufficient
without going into all the reasons ordinary code should not call it.
The name of the new function was taken from a comment in frame.h next
to reinit_frame_cache.

No new test as I think the updates to the existing test are sufficient
to show that the code is working as intended.

Simon Marchi 38b022b445 Add method/format information to =record-started
Eclipse CDT now supports enabling execution recording using two methods
(full and btrace) and both formats for btrace (bts and pt).  In the
event that recording is enabled behind the back of the GUI (by the user
on the command line, or a script), we need to know which method/format
are being used, so it can be correctly reflected in the interface.  This
patch adds this information to the =record-started async record.

Before:

  =record-started,thread-group="i1"

After:

  =record-started,thread-group="i1",method="btrace",format="bts"
  =record-started,thread-group="i1",method="btrace",format="pt"
  =record-started,thread-group="i1",method="full"

The "format" field is only present when the current method supports
multiple formats (only the btrace method as of now).

	* NEWS: Mention the new fields in =record-started.
	* common/btrace-common.h (btrace_format_short_string): New function

Tom Tromey dcd1f97951 Add self-test framework to gdb
I wanted to unit test the Rust lexer, so I added a simple unit testing
command to gdb.

The intent is that self tests will only be compiled into gdb in
development mode.  In release mode they simply won't exist.  So, this
exposes $development to C code as GDB_SELF_TEST.

In development mode, test functions are registered with the self test
module.  A test function is just a function that does some checks, and
throws an exception on failure.

Then this adds a new "maint selftest" command which invokes the test
functions, and a new dejagnu test case that invokes it.
